Answer:

Step-by-step explanation:

The function f(x) = -0.5(x + 5)³(x + 3)(x - 3) satisfies the specified conditions of decreasing at x = -5, having a local minimum at x = -3, and a local maximum at x = 3.

One possible function that satisfies the given properties is:

f(x) = -0.5(x + 5)³(x + 3)(x - 3)

Check as follows:

Decreasing at x = -5:

Taking the derivative of f(x) and evaluating it at x = -5, we have:

f'(x) = -1.5(x + 5)²(x + 3)(x - 3) - 0.5(x + 5)³

f'(-5) = -1.5(0)²(-2)(-8) - 0.5(0)³ = 0 - 0 = 0

The derivative is zero at x = -5, therefore the function has a critical point at that location. To check if it is a maximum or minimum, we can examine the second derivative.

Taking the second derivative:

f''(x) = -3(x + 5)(x + 3)(x - 3) - 3(x + 5)²(x - 3)

f''(-5) = -3(0)(-2)(-8) - 3(0)²(-8) = 0 - 0 = 0

The second derivative is also zero at x = -5. However, since the first derivative is negative for x < -5 and positive for x > -5, this means that f(x) is decreasing at x = -5.

Local minimum at x = -3:

To check if f(x) has a local minimum at x = -3, we can examine the first and second derivatives at that point.

Taking the first derivative:

f'(-3) = -1.5(2)²(0)(-6) - 0.5(2)³ = 0

The first derivative is zero at x = -3, indicating a critical point.

Taking the second derivative:

f''(-3) = -3(2)(0)(-6) - 3(2)²(-6) = 0 - 72 = -72

Since the second derivative is negative at x = -3, this confirms the presence of a local minimum.

Local maximum at x = 3:

To check if f(x) has a local maximum at x = 3, we can again examine the first and second derivatives at that point.

Taking the first derivative:

f'(3) = -1.5(8)²(6)(0) - 0.5(8)³ = 0

The first derivative is zero at x = 3, indicating a critical point.

Taking the second derivative:

f''(3) = -3(8)(6)(0) - 3(8)²(0) = 0 - 0 = 0

The second derivative is zero at x = 3, indicating that the test is inconclusive. However, since the first derivative is positive for x < 3 and negative for x > 3, this means that f(x) is decreasing at x = 3.

Therefore, the function f(x) = -0.5(x + 5)³(x + 3)(x - 3) satisfies all the given conditions.

Answer:

When p, the probability of success, is zero in a binomial distribution, the probability of getting exactly k successes in n trials is also zero for all values of k except when k is zero (i.e., when there are no successes).

So, in the case of (0.3)^0, the result would be 1, because any number raised to the power of 0 is equal to 1. Therefore, the probability of getting zero successes in a binomial distribution when the probability of success is 0.3 is 1.

Answer:

Step-by-step explanation:

To determine the length of AB, we need to find the value of x.

We are given that AC = 2x + 7, BC = x, and AB = 5x + 9.

Since B is on the line segment AC, the sum of lengths AB and BC should equal the length of AC. Therefore, we can set up the equation:

AB + BC = AC

Substituting the given values, we have:

(5x + 9) + x = 2x + 7

Simplifying the equation:

6x + 9 = 2x + 7

Bringing like terms to one side:

6x - 2x = 7 - 9

4x = -2

Dividing both sides by 4:

x = -2/4

Simplifying:

x = -1/2

Now that we have the value of x, we can substitute it back into the expression for AB to find its numerical length:

AB = 5x + 9 = 5(-1/2) + 9 = -5/2 + 9 = (18 - 5)/2 = 13/2 = 6.5

Therefore, the numerical length of AB is 6.5.

Step-by-step explanation:

The user aswati already wrote the correct answer, but I wanted to help explain why their answer is correct so that you'll understand.

According to the negative exponent rule, when a base (let's call it m) is raised to a negative exponent (let's call it n), we rewrite it as a fraction where the numerator is 1 and the denominator is the base raised to the same exponent turned positive.

Thus, the negative exponent rule is given as:

The statement which is not true include the following: (2) AABM is isosceles.

In Mathematics and Geometry, an isosceles triangle simply refers to a type of triangle with two (2) sides that are equal in length and two (2) equal angles.

By critically observing circle M shown above, we can reasonably infer and logically deduce the following true statements:

ΔABC is a right triangle.

BM = MC (radius of circle M).

mBC = m∠BMC

mAB = 1/2m∠ACB (intersecting secant theorem).

In this context, we can logically conclude that triangle ABM does not represent an isosceles triangle because it does not have two (2) sides that are equal in length.

Given the function `f(x)=1/x-1 -2` the task is to write the equation of the asymptote(s) of f and determine the x-intercept of f. Asymptotes are lines that the curve of a function approaches but never touches. There are two types of asymptotes: vertical and horizontal.

Vertical Asymptote Vertical asymptotes occur when a function approaches infinity or negative infinity at a specific value of x. This can occur in a rational function where there is a division by zero.

A vertical asymptote is found when the denominator of the rational function becomes zero. Since division by zero is undefined, it means that the rational function approaches infinity or negative infinity.

The equation of the vertical asymptote is x = a where a is the value that makes the denominator zero.

Horizontal AsymptoteA horizontal asymptote occurs when a function approaches a constant value (y) as x approaches infinity or negative infinity. A horizontal asymptote occurs when the degree of the numerator and denominator is the same.

The horizontal asymptote is found by comparing the degrees of the numerator and denominator and dividing the leading coefficient of the numerator by the leading coefficient of the denominator.3.1 Equation of the asymptotes of the equation of the vertical asymptote is x=1.

The degree of the numerator is less than the degree of the denominator. Therefore, the horizontal asymptote is y=0The equation of the horizontal asymptote is y=0.3.2 X-intercept of fTo find the x-intercept of f, set y=0.f(x) = 0= 1/(x-1) -2Add 2 to both sides2 = 1/(x-1)Take the reciprocal of both sides of the equation.1/2 = (x-1)x-1 = 2x = 3Hence, the x-intercept of the function is (3,0)

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Step-by-step explanation:

To write the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8), we first need to determine the orientation of the hyperbola.

As the y-values of the foci are the same, the foci are located horizontally from the center of the hyperbola, and therefore the hyperbola is horizontal (opening left and right).

The standard equation for a horizontal hyperbola is:

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

The center of a hyperbola is the midpoint of the vertices.

Given that the vertices are (-1, -8) and (-11, -8), we can use the midpoint formula to find the coordinates of the center:

[tex](h,k)=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)[/tex]

[tex](h, k)=\left(\dfrac{-1-11}{2},\dfrac{-8-8}{2}\right)[/tex]

[tex](h, k)=\left(-6,-8\right)[/tex]

The value of "a" is the distance between the center of the hyperbola and each vertex.  To find the value of a, calculate the distance between the x-coordinates:

[tex]a=-1-(-6)=5[/tex]

[tex]a=-6-(-11)=5[/tex]

The value of "c" is the distance between the center of the hyperbola and each focus.  Given that the foci are (7, -8) and (-19, -8), and the center is (-6, -8), to find the value of c, calculate the distance between the x-coordinates:

[tex]c = 7-(-6)=13[/tex]

[tex]c = -6-(-19)=13[/tex]

Now we have determined the values of a and c, we can use c² = a² + b² to find the value of b:

[tex]c^2 = a^2 + b^2[/tex]

[tex]13^2 = 5^2 + b^2[/tex]

[tex]169 = 25 + b^2[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

Finally, substitute the found values of a, b, h and k into the standard equation of a hyperbola:

[tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex]

[tex]\dfrac{(x-(-6))^2}{5^2}-\dfrac{(y-(-8))^2}{12^2}=1[/tex]

[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]

Therefore, the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8) is:

[tex]\boxed{\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1}[/tex]

So, the complex number equivalent to the given expression is 0 + 9i, which can also be written as 9i.

To simplify the expression 1/3(6 + 3i) - 2/3(6 - 12i), we can perform the necessary calculations.

First, let's simplify each term separately:

1/3(6 + 3i) = 2 + i (divide each term by 3)

2/3(6 - 12i) = 4 - 8i (divide each term by 3)

Now, let's substitute these simplified terms back into the original expression:

2 + i - (4 - 8i)

When subtracting complex numbers, we distribute the negative sign:

2 + i - 4 + 8i

Combine like terms:

(-2 + 2) + (i + 8i) = 0 + 9i

The expression 1/3(6 + 3i) - 2/3(6 - 12i) simplifies to 9i.

We can make the necessary computations to simplify the statement 1/3(6 + 3i) - 2/3(6 - 12i).

Let's first simplify each phrase individually:

Divide each term by 3 to get 1/3(6 + 3i) = 2 + i.

Divide each term by 3 to get 2/3(6 - 12i) = 4 - 8i.

Let's now add these abbreviated terms back into the original phrase:

2 + i - (4 - 8i)

Distributing the negative sign while subtracting complex numbers is as follows:

2 + i - 4 + 8i

combining similar terms

(-2 + 2) + (i + 8i) = 0 + 9i

A simplified version of the phrase 1/3(6 + 3i) - 2/3(6 - 12i) is 9i.

The measure of angle of arc UB is 46°

An arc is a part of the circumference.

If two arcs in circles with equal radii have the same length, then their central angles (and measures) will be equal.

To find the measure of angle of arc UB, we use the theorem that says;

angle I = 1/2( angle ZC - angle UB)

angle I = 48°

angle ZC = 142°

Therefore ;

represent angle UB by x

48 = 1/2( 142-x)

142 - x = 96

x = 142 -96

Let's visualize the movements of the man step by step:

The man starts by going 10 meters north.

He then turns left (which means he is now facing west) and covers 6 meters in that direction.

Next, he turns left again (which means he is now facing south) and walks 5 meters.

To determine the final direction of the man from the starting point, we can consider the net effect of his movements.

Starting from the north, he moved 10 meters in that direction. Then, he turned left twice, which corresponds to a 180-degree turn, effectively changing his direction by 180 degrees.

Since he initially faced north and then made a 180-degree turn, he is now facing south. Therefore, the direction he is in from the starting point is "south."
